Is Wall of Stone suppressed by Antimagic Field?

I noticed that the Wall of Stone spell includes this interesting tidbit in its first sentence (emphasized in bold):

A nonmagical wall of solid stone springs into existence at a point you choose within range.

The remainder of the spell mainly deals with how the wall can be shaped, and what happens to trapped creatures. The other relevant bit is the last paragraph:

If you maintain your concentration on this spell for its whole duration, the wall becomes permanent and can’t be dispelled. Otherwise, the wall disappears when the spell ends.

So, the wall of stone is nonmagical, but the spell can be dispelled, which causes the wall to disappear. So, is the wall magic or not? What happens if another wizard casts Antimagic Field around the wall? Will it suppress the spell within the region? And if so, what does that mean for the "nonmagical" wall created and maintained by the non-nonmagical spell?

And even though I’m pretty sure I know the answer for this one, I’ll ask it for the sake of completeness: what effect does Antimagic Field have on a wall of stone that has already been made permanent by concentrating on it for the full duration of the spell?

What is the widest gap that can be spanned by Wall of Stone?

One of the features of the Wall of Stone spell is to bridge a gap (emphasis added):

A nonmagical wall of solid stone springs into existence at a point you choose within range. The wall is 6 inches thick and is composed of ten 10-foot-by-10-foot panels. Each panel must be contiguous with at least one other panel. Alternatively, you can create 10-foot-by-20-foot panels that are only 3 inches thick.

[…]

The wall can have any shape you desire, though it can’t occupy the same space as a creature or object. The wall doesn’t need to be vertical or rest on any firm foundation. It must, however, merge with and be solidly supported by existing stone. Thus, you can use this spell to bridge a chasm or create a ramp.

If you create a span greater than 20 feet in length, you must halve the size of each panel to create supports. You can crudely shape the wall to create crenelations, battlements, and so on.

So, I want to bridge the longest possible gap using this spell. Obviously I will choose to use 10-foot-by-20-foot panels, connected lengthwise. However, I will need to "halve the size of each panel to create supports". So, do I end up with 10-foot-by-10-foot panels (for a total reach of 100 feet), or 5-foot-by-20-foot panels (for a narrower bridge reaching 200 feet)? Or something else? What is the longest gap I can bridge with these panels?

Abalative Armor and Stone Construct Interplay

Abalative Armor provides damage reduction 15/- at 10th level, once the infused item has prevented damage from a single attack even if not all the damage reduction is needed, the magic fades.

Stone Construct provides damage reduction 10/adamantine. Once the spell has prevented a total of 10 points of damage per artificer level you possess (maximum 150 points) it is discharged.

If a creature has damage reduction from more than one source, the two forms of damage reduction do not stack. Instead, the creature gets the benefit of the best damage reduction in a given situation.

My question is does the damage reduced by the Abalative Armor also reduce the total provided by Stone Construct?

Apologies if this question has been asked in the past by another.

How far away can stone shape affect stone?

Stone shape can affect an amount of stone up to 10 cubic feet + 1 cubic foot per level. If the shape you want to effect is narrow enough, you could get a lot of distance while staying under this volume. For example, a 10th level caster has a maximum of 100 cu. ft. Could such a caster touch the side of a mountain and bore an 8,000-foot-long hole through it if the hole was only 1.5 inches in diameter? The volume of this hole would be π(0.06252²)(8000) = ~98 cu. ft.³. What about reshaping a 4.5-foot cube of stone into a cylinder of similar dimensions?

Can ‘mold earth’ create climbable steps in a stone surface?

The cantrip Mold earth allows

"shapes, colors, or both to appear on the dirt or stone, spelling out words, creating images, or shaping patterns"

Could those shapes be a series of ledges and/or indentations to make a ladder for climbing out of a pit or up a stone wall? The degree to which those letters/patterns have depth isn’t specified.

The steps would disappear after 1 hr., and only two ‘areas’ of such steps could exist, but within those limits ascent could be via a series of castings of this spell:

  1. Cast and climb as high as possible on that first section.
  2. Cast again above the first area and climb as high a possible on it.
  3. Repeat.

Presumably, one would ascend at at rate of 5′ per round this way: the excavation use of mold earth specifies a 5′ cube. There is no specification of the area that can be affected by a shaping use of this spell, but 5′ x 5′ seems reasonable and consistent with that 5′ cube.

The higher level spell stone shape allows more sophisticated, and durable manipulation of stone: as a weapon or coffer, and possibly with 2 hinges and a latch. Would using mold earth to create steps steal the thunder from stone shape? I would argue that the 1 hr. duration and limits on 2 ‘areas’ (however big those might be), and the implied limit that mold earth can only work–literally–superficially (as the "shaping patterns" suggests), could be sufficient to keep this use of the cantrip from being overpowered.

However, another objection might be that the spell as written specifies creating shapes, patterns, colors, and letters suggests manipulations of the stone that are visually detectable–I could see those at more in line with creating a sign is viewable, or readable like braille, but not climbable. That is a harder argument to rebut.

Can multiple casters combine Flesh to Stone to petrify a target faster?

The flesh to stone spell states:

A creature restrained by this spell must make another Constitution saving throw at the end of each of its turns. If it successfully saves against this spell three times, the spell ends. If it fails its saves three times, it is turned to stone and subjected to the petrified condition for the duration. The successes and failures don’t need to be consecutive; keep track of both until the target collects three of a kind.

Say a wizard casts flesh to stone on an enemy, an orc to make it simple, and the orc fails the first saving throw.

Then the wizards friend, in the same round, casts a second flesh to stone spell on the poor orc, to which he also fails his saving throw. Then the wizards other friend casts a third flesh to stone in that same round on the poor orc and he fails that saving throw as well.

Does the orc fully petrify in that round? In other words, do the effects of the spells starting to petrify the orc stack with each other? He did fail 3 saving throws but it was against 3 separate spells instead of one spell.

Stone Shape, body surface area, and imprisonment [closed]

While examining various uses for stone shape and trying to double check the math on them all (such as cages, jamming doors, making poles, etc) it occurred to me that a use potentially far better than ‘encasing them in a box of rock’ would be instead to do a skin tight encasing of the individual (making it, practically speaking, impossible to move). Granted, for high (18-20) strength characters and creatures I suspect it’d be a full round action to simply break out of it, but I’m curious how the math exactly checks out, and what the exact numbers are. Surface area of a person (or a ‘medium’ creature) would need to be determined, and for small or large creatures there’d be other determinations one would have to make.

Still, it seems to me that it would be using significantly less stone than encasing someone in a box or cage.

It wouldn’t be my go to use, but I can imagine that against say some sort of goblin spell caster, or an evil elf wizard it could have some practical use.

What inspired the Ioun Stone?

While looking over the rules for Ioun Stones a question came to mind. What inspired the Ioun Stone?

It is present in nearly all editions of D&D, and also made it into Pathfinder. This Pathfinder part intrigues me, as it indicates that the Stones and the name were probably heavily inspired by an outside source. What was that source?

Can a Transmutation Wizard cast ritual transmutation spells to change the active effect of their Stone?

The text for a School of Transmutation wizard’s transmuter’s stone is as follows (PHB p.119):

Each time you cast a transmutation spell of 1st level or higher, you can change the effect of your stone if the stone is on your person.

Does this mean that if a ritual spell such as skywrite (XGE p.165) was cast, the wizard would be able to change what effect their Stone has active?
